Sure you're not thinking about IRC? We still hang out in IRC, but to my recollection ICQ was dead by by the end of the 90s. Nice setup though.
Regarding the keyboard photo on the wiki, I still can't quite see what's on fn+I. Seems to be a second caret/hat, maybe that one's a dead key, unlike the one on shift+6, but we don't have any other single use dead keys. And I can't see what's on shifted fn+I, since it's just a handful of pixels on that shot - could be tilde, could be n-dash, could be something even rarer. And what's that on Fn+J? Horizontal insertion caret, m-dash, pixelart sword?
